Abstract

A method for determining a threat against a border from objects crossing or trying to cross said border. Said method includes at least the steps of segmenting the border into border elements of uniform terrain features, infrastructure and weather conditions, collecting data of incidents occurring along a given border element, determining a threat potential for said border element, determining a protection factor for the border element, and determining a threat against the border element from the threat potential and protection factor. The method may be used for warning about an increased threat to a border, wherein the threat is compared with a threat value threshold. If the threat exceeds the threat value threshold, an alarm is issued. The method may also be used for allocating protective measures along a border.

Claims

1. A method for determining a threat against a border from objects crossing or trying to cross said border, comprising the steps of:

segmenting the border into border elements (1-n) of uniform terrain features, infrastructure and weather conditions;

collecting data of incidents occurring along a given border element (x);

determining a threat potential (tp_x) for said border element (x);

determining a protection factor (pf_x) for the border element (x); and

determining, by a computer system, a threat (t_x) against the border element (x) from the threat potential (tp_x) and protection factor (pf_x), and a threat T for the whole border comprising two or more border elements, wherein said threats are determined as;

t_x=tp_x/pf_x for the border element; and

2. The method of claim 1, wherein said threat potential is determined by dividing said incidents into categories, and further comprising the step of determining the threat potential for each category (tp_c) as:

tp_c=f·

c·

WF_TP;

and the total threat potential for the border element as;

3. The method of claim 1, wherein said protection factor is determined by assigning protection factor values to individual protection elements of terrain, infrastructure and technical protection systems, and summing said values for protection elements present in the border element.

4. The method of claim 1, further comprising:

comparing the threat to a threat value threshold; and

in response to determining the threat exceeds the threat value threshold, issuing an alarm.

5. The method of claim 1, for use in allocating protective measures along a border.

6. A system for determining a threat against a border from objects crossing or trying to cross said border, comprising:

a plurality of detectors adapted to detect incidents occurring at the border, wherein the border is segmented into border elements (1-n) of uniform terrain features, infrastructure and weather conditions;

a border management unit interfaced to the detectors;

a statistics unit coupled to the border management unit and adapted to extract the number of incidents in a border element and per threat potential category; and

a threat calculations unit coupled to the statistics unit for generating overview diagrams of threat data and trends in border situation development, wherein the threat calculations unit is configured for;

collecting data of incidents occurring along a given border element (x);

determining a threat potential (tp_x) for said border element (x);

determining a protection factor (pf_x) for the border element (x); and

determining, by a computer system, a threat (t_x) against the border element (x) from the threat potential (tp_x) and protection factor (pf_x), and a threat T for the whole border comprising two or more border elements, wherein said threats are determined as;

t_x=tp_x/pf_x for the border element; and

7. The system of claim 6, wherein the border management unit is adapted to provide an alarm in response to determining that a threat data value rises above a predefined threshold.

8. The system of claim 6, wherein the system includes a first database storing all incidents occurring at the border.

9. The system of claim 6, wherein the system includes a history database storing threat data received from said threat calculations unit.

10. The system of claim 6, wherein the border management unit includes an interface allowing manual entering of information supplied by border patrols.
